Why Haven’t We Found Alien Life Yet?

With 200 billion stars in the galaxy, many of them with planets similar to Earth, there is a strong possibility that we are not alone in this universe. If that is true, then why haven’t we met any alien life forms yet?

Video Summary

It would take approximately 100,000 light years to travel from one end of the Milky Way galaxy to the other. The Earth’s most state-of-the-art spaceships would be lucky to reach even a tenth of this speed. Even so, considering that this galaxy is about 13 billion years old, a technologically advanced alien lifeform should have reached us by now. So why haven’t we encountered them yet? Maybe aliens don’t really exist, after all. Or maybe have made too many assumptions about them. They might not be as technologically advanced as humans have been led to believe, or they may take on such a form that we have never thought of before. Mankind’s best hope for truly finding any alien lifeform would be to throw out any pre-conceived notions.
